Description

Technical Field

[0001] This utility model relates to the field of gas burner technology, specifically to a high-efficiency ejector combustion mixing system with top air intake. Background Technology

[0002] Gas burners, as key equipment for mixing gas and air and igniting them, are widely used in industrial and civil fields, such as gas stoves, boilers, heating furnaces, and wall-hung boilers. Currently, the structure of gas burners on the market mainly includes the burner body, fuel nozzle, gas passage, mixing device, ignition device, and combustion chamber.

[0003] Existing burners exhibit several problems that urgently need to be addressed during operation. Firstly, they suffer from poor airflow stability. The shape, size, and relative position of the burner's fuel nozzles and gas passages are not designed optimally, making the mixing of fuel gas and air before entering the combustion chamber susceptible to external disturbances (such as furnace pressure fluctuations and surrounding airflow disturbances), resulting in unstable airflow. This unstable airflow causes the flame to wobble, fork, or even extinguish during combustion, reducing combustion efficiency and potentially leading to incomplete combustion and increased emissions of pollutants such as carbon monoxide and nitrogen oxides.

[0004] It is evident that existing burners still have room for improvement and should be optimized to improve their structure. This includes optimizing the air intake structure, such as using swirling gas channels or specially shaped mixing chambers, to enhance the uniformity of gas-air mixing, reduce the impact of external interference on airflow stability, and ensure that the mixture has good flow characteristics and concentration uniformity upon entering the combustion chamber. This results in a more stable airflow and more uniform gas-air mixing, thereby guaranteeing the stability and reliability of the burner. Therefore, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Utility Model Content

[0005] To overcome at least one of the aforementioned defects, this utility model proposes a top-inlet high-efficiency ejector combustion mixing system, which aims to improve the gas passage of the burner. By improving the airflow, the gas and air can be mixed evenly and form a stable vortex. After the mixed gas enters the burner, it can be quickly ignited and form stable combustion, avoiding deflagration and detonation.

[0006] To achieve the above objectives, the hybrid system disclosed in this utility model can adopt the following technical solution:

[0007] A high-efficiency ejector combustion mixing system with top air intake includes a gas supply assembly and a burner. The burner has an annular mixing chamber inside, which is connected to several ejector channels that correspond to the gas supply assembly. The ejector channels form a spiral channel structure to create a swirling flow of gas entering the mixing chamber. An ejector opening is formed at the air inlet of the ejector channel. The gas supply assembly includes gas supply nozzles that correspond one-to-one with the ejector openings. A gap is left between the gas supply nozzles and the edges of the ejector openings. When the gas supply nozzles inject gas into the ejector openings, air outside the ejector openings is naturally introduced into the ejector openings and mixed with the gas in the ejector channels.

[0008] The aforementioned combustion mixing system, by adjusting the structure of the burner's ejector channel, allows the gas to mix with external air through a Venturi jet principle when it enters from the outside. The gas and air are mixed within the ejector channel, forming a swirling flow. This swirling flow results in a more uniform and stable gas mixture within the mixing chamber, ensuring stable and uniform airflow when exiting from the top of the burner. This guarantees stable combustion after ignition, improves combustion efficiency, and prevents deflagration and explosions. Furthermore, the negative pressure effect created after the gas enters the ejector channel enhances the efficiency of drawing in external air, leading to more complete combustion, reducing the emission of harmful carbon monoxide, improving the burner's thermal efficiency, and providing an effective guarantee for increasing the burner's heat load.

[0009] Furthermore, the structure at the ejector channel can be configured in various forms. The ejector opening is used to cooperate with the gas nozzle for air intake and simultaneously draw in external air for mixing, ensuring gas supply while preventing gas leakage. Its structure is not limited to a single form; here, we propose one feasible option: a flow guide hood is provided at the ejector opening. The flow guide hood forms a gradually narrowing flow chamber structure to guide external air into the ejector opening. When adopting the above scheme, the flow guide hood can be constructed in a funnel shape to form a guiding channel for external airflow. The gas supply nozzle can extend into the ejector opening. When gas is injected into the ejector opening, a high-speed jet is formed, creating a natural negative pressure around the jet, thereby drawing external air into the ejector opening and forming a mixed gas with the gas. The mixed gas continues to flow forward, maintaining this natural intake and mixing state.

[0010] Furthermore, to facilitate the introduction of external air, the ejector channel can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the ejector channel forms a throat inward from the ejector opening, and a diffusion section is formed during the diffusion process from the throat into the mixing chamber, with the inner diameter of the diffusion section gradually increasing. When the above scheme is adopted, as the mixed gas is transported through the throat to the diffusion section, the diffusion expansion of the space promotes the formation of negative pressure, improving the efficiency of mixed gas entry, and thus also improving the efficiency of drawing in external air.

[0011] Furthermore, after the ejector channels are installed, they promote the mixing of fuel gas and air by forming a swirling flow, maintaining uniformity and stability within the mixing chamber to ensure balanced and stable combustion. The number of ejector channels is not limited; here, an optimization is proposed, suggesting one feasible option: two ejector channels symmetrically arranged on the outer plane of the mixing chamber. These two channels guide the airflow into the mixing chamber, forming a 360° rotating swirling gas flow. Using this scheme, the two ejector channels can generate two airflows, which, after passing along a predetermined path, form a swirling flow. In other schemes, the number of ejector channels can be varied. By setting more ejector channels, the intake efficiency and the stability of the formed swirling flow can be increased. These additional ejector channels can also be configured with a certain curvature and evenly spaced on the circumference.

[0012] Furthermore, after adjusting the structure of the lower ejector channel, the mixed gas flow enters the burner. The burner continues to guide the gas flow to maintain its stability. The burner can employ various designs, and its structure is not limited to a single design. Here, we optimize and propose one feasible option: the burner includes a fixed plate, with a flame cap positioned above the fixed plate. The flame cap covers the fixed plate and seals it to form the mixing chamber. A central hole connecting the ejector channel is provided at the fixed plate. In this design, the fixed plate connects the lower ejector channel and the upper mixing chamber. The mixed gas in the lower ejector channel flows into the upper mixing chamber, where it flows continuously and stably through the guiding structure, forming a swirling flow. Finally, it is output outward through the vents on the flame cap, forming stable combustion.

[0013] Furthermore, to further improve combustion stability, the mixed gas is guided within the mixing chamber to enhance its stability. This can be achieved by optimizing the internal structure of the mixing chamber, which is not limited to a single structure. Here, we propose one feasible option: a flow divider is installed within the mixing chamber, dividing it into an upper and lower chamber. Several air holes are provided on the flow divider, allowing gas from the lower chamber to enter the upper chamber. With this scheme, the flow divider forms an annular flow-dividing surface. The mixed gas entering the mixing chamber initially resides in the lower chamber, then passes through the flow-dividing surface before entering the upper chamber.

[0014] Furthermore, the flow divider can be implemented using various schemes to separate the mixing chamber, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the flow divider includes an intermediate cylinder that extends downward and cooperates with a fixed plate; a horizontal annular panel is formed at the upper end of the intermediate cylinder, and the air holes are located on the annular panel. When the above scheme is adopted, the intermediate cylinder and the replacement panel are integrally formed; the air holes on the annular panel can be constructed as elongated strips, and the air holes form a certain tilt angle. When the swirling gas reaches the air holes, it is output outward along the air holes to form a more stable airflow and combustion.

[0015] Furthermore, to improve combustion efficiency and provide a larger combustion area, the burner structure can be optimized to form a larger flame zone. Various solutions can be adopted, and the structure is not limited to a single one. Here, we propose one feasible option: the burner further includes a central combustion assembly, which includes a central flame cap structure located in the middle of the annular mixing chamber. A central mixing chamber is formed within the central flame cap structure, and the central mixing chamber connects to a central ejector channel and receives gas supply from the gas supply assembly. When adopting the above solution, the central combustion assembly can also use an annular mixing chamber and an ejector channel with a certain curvature, or it can use a conventional straight-through ejector channel and a straight-through mixing chamber. The central combustion assembly forms an inner ring flame. The mixed gas output from the annular mixing chamber mentioned above forms an outer ring flame after ignition.

[0016] Furthermore, the gas supply assembly is used to supply gas to the burner and can be adapted to multiple ejector channels. Its structure is not uniquely limited; here, optimization is proposed, and one feasible option is suggested: the gas supply assembly includes a base, on which a gas supply pipeline is provided, and several gas supply branch pipes are provided on the gas supply pipeline. The gas supply nozzles are located at the gas supply branch pipes. In this scheme, the gas supply pipeline extends on the base, and gas supply branch pipes are provided at corresponding ejector opening positions. The gas supply nozzles on the gas supply branch pipes cooperate with the corresponding ejector openings to achieve gas intake.

[0017] Furthermore, when the burner and the gas supply assembly are coupled, multiple supports can be used to maintain stability. The structure is not limited to a single type. Here, we propose one feasible option: several support portions are formed on the base, and corresponding support portions are formed on the burner. When the burner and the gas supply assembly are coupled, the support portions and support portions fit together. In this scheme, both the support portions and the support portions are corresponding protruding structures.

[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0019] This invention optimizes the structure of the combustion mixing system by using an ejector channel to guide the combustion gas into the mixing chamber. During this process, external air is introduced using the jet principle to form a mixed gas, resulting in a simpler structure. After the mixed gas enters the mixing chamber, it forms a swirling flow, thereby improving the uniformity of the mixed gas. This ensures the stability of combustion and improves combustion efficiency, while also preventing phenomena such as deflagration and knocking. Attached Figure Description

[0040] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this embodiment.

[0041] In view of the problems of low combustion efficiency, unstable and uneven combustion process, and easy occurrence of deflagration and knocking in the combustion system of the prior art, the following embodiments are optimized and overcome the defects of the prior art.

[0042] Example

[0043] like Figures 1-17As shown, this embodiment provides a high-efficiency ejector combustion mixing system with top air intake, including a gas supply component 2 and a burner 1. The burner 1 forms an annular mixing chamber, which is connected to several ejector channels 3 corresponding to the gas supply component 2. The ejector channels 3 form a spiral channel structure to make the gas entering the mixing chamber form a swirling flow. An ejector opening 301 is formed at the air inlet of the ejector channel 3. The gas supply component 2 includes a gas supply nozzle 203 corresponding to the ejector opening 301. There is a gap between the gas supply nozzle 203 and the edge of the ejector opening 301. When the gas supply nozzle 203 injects gas into the ejector opening 301, the air outside the ejector opening 301 is naturally introduced into the ejector opening 301 and mixed with the gas in the ejector channel 3.

[0044] Preferably, in this embodiment, the burner 1 includes an outer ring combustion assembly 101 and a central combustion assembly 102.

[0045] The combustion mixing system disclosed in this embodiment adjusts the structure of the ejector channel 3 of the burner 1. When the gas enters from the outside, it is mixed with the outside air through the Venturi jet principle. The gas and air are mixed in the ejector channel 3 and a swirling flow is formed under the action of the ejector channel 3. The gas after the swirling flow becomes uniform and stable in the mixing chamber. When the gas exits from the top of the burner 1, the airflow remains stable and uniform, thereby ensuring stable combustion after ignition, improving combustion efficiency, and avoiding deflagration and explosion sounds. After the gas is ejected into the ejector channel 3, a negative pressure effect is formed, which also improves the efficiency of drawing in outside air, allowing the gas to burn more completely, thereby reducing the emission of harmful carbon monoxide, improving the thermal efficiency of the burner, and providing an effective guarantee for increasing the thermal load of the burner.

[0046] Preferably, in this embodiment, after the gas and air enter the ejector channel 3, they are transported along the channel and rotate within the mixing chamber to generate a vortex. This rotation generates a suction force in the direction of the ejector channel, which draws more gas and air into the mixing chamber from the gas supply nozzle 203. Drawing in more gas increases the heat load, while drawing in more air reduces carbon monoxide production and improves thermal efficiency.

[0047] Preferably, in this embodiment, the ejection channel 3 includes an upper housing 302 and a lower housing 303, which are joined together to form a seal through bending and interlocking.

[0048] The structure at ejector channel 3 can be configured in various forms. Its ejector opening 301 is used to cooperate with the gas nozzle for air intake and simultaneously draw in external air for mixing, ensuring gas supply while preventing gas leakage. Its structure is not limited to a single form. This embodiment optimizes and adopts one feasible option: a flow guide shroud is provided at the ejector opening 301. The flow guide shroud forms a gradually narrowing flow cavity structure to guide external air into the ejector opening 301. When the above scheme is adopted, the flow guide shroud can be constructed in a funnel shape to form a guiding channel for external airflow. The gas supply nozzle 203 can penetrate into the ejector opening 301. When gas is injected into the ejector opening 301, a high-speed jet is formed, creating a natural negative pressure around the jet, thereby drawing external air into the ejector opening 301 and forming a mixed gas with the gas. The mixed gas continues to flow forward, maintaining this natural intake and mixing state.

[0049] To facilitate the introduction of external air, the ejector channel 3 can be constructed in various forms, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the ejector channel 3 forms a throat 304 inward from the ejector opening 301, and a diffusion section 305 is formed during the diffusion process from the throat 304 into the mixing chamber, with the inner diameter of the diffusion section 305 gradually increasing. When the above scheme is adopted, when the mixed gas is transported through the throat 304 to the diffusion section 305, the diffusion expansion of the space can promote the formation of negative pressure, improve the efficiency of mixed gas entry, and thus also improve the efficiency of drawing in external air.

[0050] After the ejector channels 3 are installed, they promote the mixing of fuel gas and air by forming a swirling flow, maintaining uniformity and stability within the mixing chamber to ensure balanced and stable combustion. The number of ejector channels 3 is not limited to a single factor. This embodiment optimizes and adopts one feasible option: the number of ejector channels 3 is two, symmetrically arranged on the outer plane of the mixing chamber. The two ejector channels 3 guide the airflow into the mixing chamber and form a 360° rotating swirling gas flow. With the above scheme, the two ejector channels 3 can form two airflows, which are transmitted along a set path to form a swirling flow. In other schemes, the number of ejector channels 3 can be changed. By setting more ejector channels 3, the efficiency of air intake and the stability of the formed swirling flow can be increased. The more ejector channels 3 are also set with a certain curvature and are evenly spaced on the circumference.

[0051] After adjusting the structure of the lower ejector channel 3, the mixed gas flow enters the burner 1. The burner 1 continues to guide the gas flow to maintain its stability. The burner 1 can employ various designs, and its structure is not limited to a single design. This embodiment optimizes and adopts one feasible option: the burner 1 includes a fixed plate 8, with a flame cap 4 positioned above it. The flame cap 4 covers and seals the fixed plate 8, forming the mixing chamber. A central hole connecting the ejector channel 3 is provided at the fixed plate 8. Using this design, the fixed plate 8 connects the lower ejector channel 3 and the upper mixing chamber. The mixed gas in the lower ejector channel 3 flows into the upper mixing chamber, where it flows steadily and forms a swirling flow through the guiding structure. Finally, it is output outward through the air hole 703 on the flame cap 4, forming stable combustion.

[0052] Preferably, in this embodiment, several arc-shaped air inlets 801 are formed at the center hole of the fixing plate 8. When the mixed gas reaches the diffusion section 305 through the ejector channel 3 and mixes and swirls, it enters the mixing chamber upward through the arc-shaped air inlets 801.

[0053] To further improve combustion stability, the mixed gas is further guided within the mixing chamber, thereby enhancing its stability. This can be achieved by optimizing the internal structure of the mixing chamber. The structure is not uniquely limited; this embodiment optimizes the process and adopts one feasible option: a flow divider 7 is provided within the mixing chamber, dividing it into an upper chamber 401 and a lower chamber 402. The flow divider 7 has several air holes 703 that allow gas from the lower chamber 402 to enter the upper chamber 401. With this scheme, the flow divider 7 forms an annular flow-dividing surface. The mixed gas entering the mixing chamber first resides in the lower chamber 402, and after passing through the flow-dividing surface, enters the upper chamber 401.

[0054] The flow divider 7 can be implemented using various schemes to form the separation of the mixing chamber, and its structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the flow divider 7 includes an intermediate cylinder 701, which extends downward and cooperates with the fixing plate 8; a horizontal annular panel 702 is formed at the upper end of the intermediate cylinder 701, and the air hole 703 is located on the annular panel 702. When the above scheme is adopted, the intermediate cylinder 701 is integrally formed with the replacement panel; the air hole 703 on the annular panel 702 can be constructed as an elongated strip, and the air hole 703 forms a certain inclined angle. When the swirling gas reaches the air hole 703, it is output outward along the air hole 703 to form a more stable airflow and combustion.

[0055] To improve combustion efficiency and provide a larger combustion area, the structure of burner 1 is optimized to form a larger flame zone. Various solutions can be adopted, and the structure is not limited to a single one. This embodiment optimizes and adopts one feasible option: the burner 1 further includes a central combustion assembly 102, which includes a central flame cap structure 1021 located in the middle of the annular mixing chamber. A central mixing chamber is formed within the central flame cap structure 1021, and the central mixing chamber connects to a central ejector channel 1022 and receives gas supply from the gas supply assembly 2. When adopting the above solution, the central combustion assembly 102 can also use an annular mixing chamber and an ejector channel 3 with a certain curvature, or it can use a conventional straight-through ejector channel 3 and a straight-through mixing chamber. The central combustion assembly 102 is used to form an inner ring flame. The mixed gas output from the annular mixing chamber mentioned above forms an outer ring flame after ignition.

[0056] The gas supply assembly 2 is used to supply gas to the burner 1 and can be adapted to multiple ejector channels 3. Its structure is not uniquely limited; this embodiment optimizes and adopts one feasible option: the gas supply assembly 2 includes a base, a gas supply pipe 201 is provided on the base, and several gas supply branch pipes 202 are provided on the gas supply pipe 201. The gas supply nozzle 203 is located at the gas supply branch pipe 202. In this configuration, the gas supply pipe 201 extends from the base, and a gas supply branch pipe 202 is provided at the corresponding ejector opening 301. The gas supply nozzle 203 on the gas supply branch pipe 202 cooperates with the corresponding ejector opening 301 to achieve gas intake.

[0057] When the burner 1 and the gas supply assembly 2 are engaged, multiple supports can be used to maintain stability. The structure is not uniquely limited. This embodiment optimizes the process and adopts one feasible option: several support portions 6 are formed on the base, and corresponding support portions 5 are formed on the burner 1. When the burner 1 and the gas supply assembly 2 are engaged, the support portions 5 and the support portions 6 are in close contact. In this scheme, both the support portions 6 and the support portions 5 are corresponding protruding structures.

[0058] The above are the embodiments listed in this example. However, this example is not limited to the optional embodiments described above. Those skilled in the art can arbitrarily combine the above methods to obtain other various embodiments. Anyone can derive other various forms of embodiments under the guidance of this example. The above specific embodiments should not be construed as limiting the scope of protection of this example. The scope of protection of this example should be defined in the claims.
